This invention relates to a method of packaging frozen to a substantially solid state have heretofore been provided in order'to effect their storage and shipment. Usually these take the form of or include either a rigid metallic container having a tightly fitting closure or rigid thick-paper containers that are self-sustaining and form-retaining without the contents serving as a necessary part thereof in order to serve as a storage and shipping container therefor. These types of con tainers are comparatively expensive both from a production and handling standpoint. In fact, the metal containers must be returned to the menufacturer for re-use and this constitutes a substantial handling expense in connection therewith. The other type of self-sustag and fo-retaming thick paper containers not only are com= paratively expensive, but also involve a handling cost owing to the fact that they require appreciable space to maintain a stools thereof available for the requirements of the ice cream manufac= turer and entail some labor in the assembly thereof while the contents are being poured therein. Pressure filling methods have also been used in connection with special collapsible ice cream wrappers for individual servings, but this involves special equipment and is not adaptable to large quantity units such as two and one-half and five gallon units.

()ne object of the present invention is to provide a more simple and less expensive method of packaging normally liquid materials frozen to a substantially solid state for storage and shipment purposes.

Another object is to provide a novel method of packaging including a collapsible non-rigid container which serves as a confining medium for normally liquid material frozen to a substantially solid state and serving as a necessary element thereof to render the container collapsible for that purpose.

Still another object is to provide a method of packaging including a non-rigid collapsible-selfwith normally liquid material frozen to a suhs= tlally solid state to constitute a self-susta and form-retaining unit for storage and shipment purposes.

A further object is to provide a novel rnethod of packaging which utilizes an inexpensive thin non= rigid collapsible container for use as a r medium for normally liquid material frozen to a substantially solid state.

Still another object is to provide an improved method of packaging which consists in enabling the use of comparatively inexpensive storage d shipping containers for normally liquid subsnces frozen to a substantially solid state to render the container rigid in conjunction therewith.

Still a further object is to provide an proved packaging method capable of utilizing a thin non rigid collapsible seli closing container in coniunotion with normally liquid material frozen to a substantially solid state to render such selfish-a taining and form-retaining for storage and ship= ment purposes.

Other objects and advantages will appear from the following description of an illustrative em bodiment of the present invention.

The structure select/ed tor illustration cxemplh fies a method of filling an improved bulls container for normally liquid material frozen to a substan tially solid state. It comprises essentially the prcyislon of a paper container to which is creased and folded intermediate the side walls thereof on at H and ii to present a thin non-rigid paper collapsed container suficieht in size to either 2 /2 gallons. 5 gallons, or any multiple closing paper container that can be readily filled q anti y of l y iq d m rl lfrozm to a its enclosed plastic contents to refrigeration to render the container and contents self-sustaining and form-retaining for storage and shipping purposes.

2. A method of packaging comparatively large units of normally liquid material frozen to a substantially solid state which consists in first opening a non-rigid collapsible closed-end paper container of such thinness that is normally not self-sustaining nor form-retaining, then gravity filling the container with a normally liquid material frozen to a plastic state, folding the open end of the container to form an enclosure for the contents, and then subjecting the container with its enclosed plastic contents to refrigeration for converting the contents to a substantially frozen solid state to render the container and contents-self-sustaining and form-retaining for storage and shipping purposes.

5.

A method of packaging comparatively large units of normally liquid material frozen to a substantially solid state whichconsists in first opening a non-rigid collapsible closed-end paper container of such thinness that is not normally, selfsustaining nor form-retaining, then placing the collapsible container in a, preformed rigid form to serve as a temporary liner therefor, then filling the container with a normally liquid material frozen to a plastic state by passage through a discharge opening that is substantially smaller in diameter than the opening in the container to permit the free escape of air, folding theopen end of the container, then tying the folded end of the container to form an enclosure, then sub- 'jecting the container with its enclosed plastic contents to refrigeration to render the container and its contents self-sustaining and form-retaining, and then removing the container with its frozen contents from said rigid form for storage -.or shipment independent thereof.
